Ingredients
Cauliflower Mash
-
2 large heads cauliflower, broken into florets
-
1½ cups shredded Parmesan cheese
-
1 cup shredded Colby–Monterey Jack cheese
-
6 tablespoons butter, cubed
-
¾ teaspoon garlic salt
-
½ teaspoon Montreal steak seasoning
Topping
-
1 cup Italian-style panko breadcrumbs
-
¼ cup butter, melted
Instructions
-
Preheat oven to 350°F.
-
Place cauliflower florets in a large pot and add water to cover. Bring to a boil, then reduce heat and simmer uncovered for 10–12 minutes, or until very tender. Drain well.
-
Transfer cauliflower to a large bowl and mash until mostly smooth. Stir in Parmesan cheese, Colby–Monterey Jack, cubed butter, garlic salt, and Montreal steak seasoning until creamy and well combined.
-
Spread mixture into a greased 3-quart or 9×13-inch baking dish.
-
In a small bowl, mix panko breadcrumbs with melted butter until evenly coated. Sprinkle evenly over the cauliflower.
-
Bake uncovered for 40–50 minutes, until heated through and the topping is golden brown.
-
Let rest for 5–10 minutes before serving.
Notes
-
For extra-smooth texture, mash with a hand mixer or use a food processor.
-
Swap cheeses with sharp cheddar, Gruyère, or mozzarella if desired.
-
This dish pairs especially well with ham, roast chicken, or beef.
